30-Piece 120 Grit Diamond Drill Bits Kit – 1mm, 2mm & 3mm Diameters – Electroplated For Rocks, Sea Glass, Shells & Ceramic Jewelry

About This Product

If you do jewelry making, lapidary, or any kind of craft with hard materials, this diamond drill bit kit is a must-have.
You get 30 bits total – 10 each of 1mm, 2mm, and 3mm diameters – all with a 120 grit (medium) electroplated diamond coating.

The shank is about 1/8 inch, so they fit most rotary tools and flex shafts.
Total length is 45mm with a drilling depth of about 8mm.

They're ideal for drilling holes in rocks, sea glass, ceramics, shells, and gemstones.
Just remember: always keep the drilling point wet with water – otherwise the diamond coating will overheat and wear out fast.

Also, don't press too hard, or you might snap the bit.

Comes in a neat storage box, so everything stays organized.
Solid set for crafters at any level.
